Secure messenger app

Liberdus is a decentralized messaging network implemented as a layer-one blockchain, designed to provide secure, censorship-resistant digital communication without reliance on centralized servers or trusted intermediaries. Rather than treating messages as off-chain data managed by application providers, Liberdus models messages as cryptographically secured transactions that are validated and recorded by a decentralized network of nodes. This approach allows message delivery, access control, and spam resistance to be enforced through protocol rules and consensus rather than platform moderation. The network combines cryptographic security, economic mechanisms, and decentralized governance to create a communication system where privacy, availability, and rule enforcement are determined by transparent protocol logic rather than centralized infrastructure operators.

Openbands is an anonymous and verified employee forum. Users can sign in with their work email and prove their company affiliation while preserving their identiy. After signing up users can participate in anonymous conversations. We are using Noir zkJWT library to prove a user is authorized to log into a company email. The user generated the proof client-side and submits it onchain, where it's verified and stored. Our aim to build a global community powered by truth and ran by professionals. In a future version, we want companies to post job listings. The fees collected for posting a job will be distributed to active contributors.

A spam-resistant instant messaging application for private and anonymous communication

A simple and private way to exchange bitcoin for national currencies.

Secure is a fully serverless, privacy-first messaging platform built on Tor hidden services, designed for true peer-to-peer communication with zero centralized infrastructure. Unlike traditional messaging apps, Secure does not rely on servers, relays, or push notification systems. Messages are transmitted directly between devices over the Tor network, eliminating third-party intermediaries and significantly reducing metadata exposure. There are no phone numbers, emails, or accounts required—identity is created and stored locally on the user’s device. The platform leverages advanced cryptography, including post-quantum hybrid key exchange and forward secrecy, ensuring long-term protection against both current and future threats. All data is encrypted at rest, and communication is end-to-end encrypted by default. Key features include: Serverless P2P messaging over Tor hidden services No accounts, phone numbers, or email required Post-quantum encryption with forward secrecy Private group messaging with no central coordination layer Metadata-minimizing architecture by design Cross-platform support (iOS and Android) Secure local storage with encrypted database Secure Pay (multi-chain): Send and receive cryptocurrency across multiple blockchains directly within the app, with privacy-first design and no custodial control Secure is built for users who demand maximum privacy, censorship resistance, and control over their data. By removing centralized points of failure and operating entirely over Tor, Secure provides a communication layer that cannot be easily surveilled, blocked, or shut down.
